directly selecting a node with submenu

A
-> A.1
-> A.2

Selecting a menu item with a submenu (A) will always call _process_breadcrums() on all submenu items (A.1, A.2)
If non of the submenu items is selected, the parent node is also not selected.

Selecting A.1 will work and select A.
Directly selecting A will not mark A as selcted, as neither A.1 nor A.2 are selected.
